Abstract

The nonlinear response of low and medium-rise special moment-resisting steel frames to simulated ground motion acceleration is compared with the response to actual ground motion records. A spectral-representation-based simulation algorithm was used to generate the simulated time histories. It is shown that in most cases the simulated time histories yield acceptable mean values for the response parameters with less dispersion. This means that only a few simulated accelerograms may be used to estimate the mean response parameters for a wide range of structures with different frequencies. The use of artificial acceleration time histories generated by this method is an efficient alternative to using scaled actual ground motion records.
